Embodiment Construction
[0013] Such as Figure 1 to Figure 3 Shown, the production technology of EPP lightweight seat of the present invention comprises the following steps:
[0014] (1) Bending a steel pipe or a strip steel plate to form a seat outline skeleton 1 with the overall outline of the seat. The seat outline skeleton 1 includes a backrest outline skeleton 2 and a seat cushion outline skeleton 3, and a backrest outline skeleton 2 It is connected with the outer contour frame 3 of the seat cushion to form an integral structure, and the discontinuity of the steel pipe or strip-shaped steel plate in the outer contour frame 2 of the backrest and the outer contour frame 3 of the seat cushion is welded so that the outer contour frame 1 of the seat is connected into a continuous integrated structure; The steel pipe or strip steel plate is spring steel. In this embodiment, the steel pipe made of spring steel is bent to obtain the seat outer profile frame 1, and the joints of the steel pipes are conne...

The production process of the EPP lightweight seat of the present invention includes the following steps: (1) Bending a steel pipe or a strip steel plate to form a seat outline skeleton with the overall outline of the seat, and welding the discontinuous parts of the steel pipe or strip steel plate Make the seat outer contour skeleton connect into a continuous integrated structure; (2) Position the seat outer contour skeleton in the EPP foaming mold, inject EPP foam material into the EPP foaming mold, and make the seat outer contour skeleton and The EPP materials are foamed together to form an EPP seat frame assembly with a cushion frame and a backrest frame; (3) Position the EPP seat frame assembly in the foam foaming mold, inject foamed foam into the foam foaming mold, Foaming the EPP seat frame assembly and foam together to form a seat foam assembly; (4) Putting the seat cover assembly on the seat foam assembly coat to obtain an EPP lightweight seat. The process of the invention can effectively reduce the quality of the seat and meet the lightweight requirements of auto parts.
Description
technical field [0001] The invention relates to the field of auto parts, in particular to a production process of a seat. Background technique [0002] Existing car seats usually include a seat frame, a seat foam and a seat cover, the seat foam is wrapped outside the seat frame, and the seat cover is covered outside the seat foam. The seat frame is formed by processing steel pipes, steel plates, and steel wires. The structure of the seat frame is complex, and the parts are connected to each other by welding or riveting. The production process of the seat frame is complex, the processing cost is high, and the overall quality of the seat is relatively large. With the continuous promotion of new energy vehicles, various auto parts are required to be lightweight, and the above-mentioned existing car seats cannot meet the lightweight requirements. Contents of the invention [0003] The object of the present invention is to provide a production process for EPP lightweight seat...
